Description

Technical Field

[0001] This utility model relates to the field of food preservation technology, specifically to a quick-frozen food preservation device. Background Technology

[0002] Quick-frozen foods are processed by rapidly freezing at low temperatures (below -18°C). This process prevents the loss of moisture and juices from the food's tissues, and at such low temperatures, microorganisms essentially do not multiply, ensuring food safety. Currently, common storage devices for quick-frozen foods are ordinary freezers or refrigerator freezers, but these traditional storage devices have some shortcomings.

[0003] Traditional equipment has a fixed internal space layout, which cannot be flexibly adjusted according to the shape and size of different frozen foods, resulting in low space utilization. For example, some larger frozen foods may not be able to be placed due to insufficient spacing between shelves; while some small-packaged frozen foods may waste space due to excessive spacing between shelves.

[0004] Therefore, it is necessary to provide a quick-frozen food preservation device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a quick-frozen food preservation device to solve the problems mentioned in the background art.

[0029] Please see Figures 1-5 One embodiment provided by this utility model:

[0030] A quick-frozen food preservation device, comprising:

[0031] The quick-freezing cabinet 1 has support frames 2 on both sides inside the quick-freezing cabinet 1. Several fixing holes 8 are evenly and uniformly opened on the opposite surfaces of the two support frames 2. Several shelves 7 are set on the opposite surfaces of the two support frames 2. An L-shaped card plate 13 is fixedly installed on the side of the shelf 7 close to the support frame 2, and the L-shaped card plate 13 is engaged with the fixing hole 8.

[0032] The two support frames 2 have positioning grooves 9 on their opposite sides below the fixing holes 8. The shelf 7 has an installation groove 17 on the side below the support frame 2. The bottom of the shelf 7 has a through groove 16, which is connected to the inside of the installation groove 17. A positioning post 14 is slidably inserted into the installation groove 17, and the positioning post 14 is engaged with the positioning groove 9.

[0033] A spring 18 is fixedly installed at one end of the positioning post 14 inside the mounting groove 17, and an operating block 15 is fixedly installed on the outer wall of the other end of the positioning post 14 inside the mounting groove 17. The operating block 15 extends through the through groove 16 to the bottom of the shelf 7.

[0034] A horizontal rail 4 is fixedly installed at the top inside the quick-freezing cabinet 1. An adjusting screw 6 is rotatably installed inside the horizontal rail 4. The outer wall of the adjusting screw 6 is provided with symmetrically distributed left-hand and right-hand threads. A symmetrically distributed adjusting block 5 is sleeved on the outer wall of the adjusting screw 6, and the adjusting block 5 is slidably installed on the horizontal rail 4. Two support frames 2 are fixedly installed at the bottom of the two adjusting blocks 5 respectively. A worm gear 11 is rotatably installed inside the horizontal rail 4 above the adjusting screw 6, and the front end of the worm gear 11 passes through the horizontal rail 4 and extends to the front of the horizontal rail 4. A knob 12 is fixedly installed at the front end of the worm gear 11. A worm wheel 10 is fixedly installed on the outer wall of the adjusting screw 6, and the worm wheel 10 meshes with the worm gear 11.

[0035] In one embodiment, several limiting telescopic rods 3 are fixedly installed on both sides inside the quick-freezing cabinet 1, and the telescopic ends of the limiting telescopic rods 3 are fixedly connected to the support frame 2 at the corresponding positions, ensuring that the support frame 2 can only move along the preset direction, avoiding unnecessary shaking, offset or misalignment, and ensuring the stability and accuracy of the movement of the shelf 7.

[0036] In one preferred embodiment, the end of the positioning post 14 near the support frame 2 is inclined, and the positioning post 14 is adapted to the positioning groove 9, which facilitates the quick installation of the shelf 7.

[0037] In one embodiment, the adjusting block 5 is T-shaped and is adapted to the horizontal rail 4, which can ensure that the adjusting block 5 slides stably on the horizontal rail 4, prevent the adjusting block 5 from falling off, and ensure the reliability of the horizontal spacing adjustment of the shelf 7.

[0038] In one preferred embodiment, the adjusting block 5 has a threaded hole that matches the adjusting screw 6, and the adjusting block 5 is threadedly connected to the adjusting screw 6 through the threaded hole.

[0039] The working principle of this utility model is as follows: Parts not described in this device are the same as or can be implemented using existing technology. In use, a tray containing food is inserted into a set of horizontally positioned shelves 7. The vertical position of the shelves 7 on the support frame 2 can be adjusted according to the size of the food. Specific operation is as follows: The user directly removes the shelf 7 and moves the operating block 15 below it. The operating block 15 drives the positioning post 14 to slide into the mounting groove 17, simultaneously compressing the spring 18. As the positioning post 14 moves, it disengages from the positioning groove 9, thus losing its engaging relationship. At this point, the shelf 7 is moved upwards, causing the L-shaped clamping plate 13 to slide upwards on the fixing hole 8 until the top of the L-shaped clamping plate 13 contacts the top of the inner wall of the fixing hole 8. Then, the shelf 7 is pulled outwards to remove the L-shaped clamping plate 13 from the fixing hole 8, thus completing the disassembly of the shelf 7. Subsequently, the shelf 7 is installed in a suitable position on the support frame 2. When installing the shelf 7, the L-shaped clamping plate 13 can be directly inserted into the fixing hole 8, and then the shelf 7 can be moved downwards so that the L-shaped clamping plate 13 is engaged with the fixing hole 8. At the same time, the inclined end of the positioning post 14 contacts the outer wall of the support frame 2, and the positioning post 14 will automatically move into the mounting groove 17 and compress the spring 18 until the shelf 7 is installed in place. At this time, the positioning post 14 will be engaged into the corresponding positioning groove 9 under the elastic restoring force of the spring 18, thus completing the fixed installation of the shelf 7 on the support frame 2. Through the detachable design of the shelf 7 on the support frame 2, the user can adjust the position of the shelf 7 on the support frame 2 at will during use, effectively improving space utilization. In addition, the detachable structure of the shelf 7 is simple in design and easy to operate, making it convenient for users to quickly assemble, disassemble and adjust the position.

[0040] In use, the lateral distance between the shelves 7 on both sides inside the quick-freezing cabinet 1 determines the size of the trays that can be placed on the shelves 7. If the lateral position of the shelves 7 is fixed, a tray of the appropriate size must be used. However, when the user uses the device and the tray size is small, the spacing between the shelves 7 can be adjusted by rotating the knob 12. Rotating the knob 12 drives the worm gear 11 to rotate. Since the worm gear 11 and the worm wheel 10 mesh with each other, the rotation of the worm gear 11 causes the worm wheel 10 to drive the adjusting screw 6 to rotate. The adjusting screw 6 is provided with left-hand and right-hand threads. Utilizing the thread transmission principle, combined with the sliding fit between the adjusting block 5 and the horizontal rail 4, the two adjusting blocks 5 can move stably relative to each other or in opposite directions. The movement of the adjusting blocks 5 drives the support frame 2 to move, which in turn drives the shelves 7 to move, realizing the adjustment of the lateral spacing between the shelves 7 on both sides inside the quick-freezing cabinet 1. This allows the device to adapt to trays of different sizes, significantly improving the versatility and practicality of the device.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
